Investigation of transdermal permeation behavior of diclofenac sodium microemulsion by confocal laser scanning microscopy
Purpose: To investigate the in vitro skin permeation and transdermal behavior of diclofenac sodium using a new system of microemulsion.
Methods: Diclofenac sodium was incorporated into oil-in-water (o/w) and water-in-oil (w/o) microemulsions consisting of a 2:1 ratio of Cremophor RH 40: Span 80 as surfactant phase, ethylhexyl palmitate as oil phase, and a 2:1 ratio of water: isopropanol as aqueous phase. Franz diffusion cell was used to determine the in vitro skin permeation. Morphology of microemulsions were characterized by transmission electron microscopy (TEM). The depth of penetration distribution was visualized by fluorescently labelling, and observing using confocal laser scanning microscopy (CLSM).
Results: The o/w type provided an enhanced permeation flux, with more than a 3- fold increase in permeability coefficient across skin as compared with w/o type. The morphology characterization indicated that both o/w and w/o type were nano-sized and spherical in shape. It was observed by CLSM that o/w type significantly facilitated the penetration of sulforhodamine B (SRB) to the deeper layers of the skin (220 μm) than w/o type (150 μm).
Conclusion: This study demonstrates that diclofenac sodium microemulsion can be transdermal, and the skin penetration depends on the microstructure and composition of microemulsion.
期刊介绍:
The international journal of the Polish Pharmaceutical Society is published in 6 issues a year. The journal offers Open Access publication of original research papers, short communications and reviews written in English, in all areas of pharmaceutical sciences. The following areas of pharmaceutical sciences are covered: Analysis, Biopharmacy, Drug Biochemistry, Drug Synthesis, Natural Drugs, Pharmaceutical Technology, Pharmacology and General.
A bimonthly appearing in English since 1994, which continues “Acta Poloniae Pharmaceutica”, whose first issue appeared in December 1937. The war halted the activity of the journal’s creators. Issuance of “Acta Poloniae Pharmaceutica” was resumed in 1947. From 1947 the journal appeared irregularly, initially as a quarterly, then a bimonthly. In the years 1963 – 1973 alongside the Polish version appeared the English edition of the journal. Starting from 1974 only works in English are published in the journal. Since 1995 the journal has been appearing very regularly in two-month intervals (six books a year). The journal publishes original works from all fields of pharmacy, summaries of postdoctoral dissertations and laboratory notes.
